The “careful part” is in exposing your hands to this particular type of glue.
Why? Forget getting any glue residue off your hands UNLESS your glue dispursing hand is protected with at least one latex glove. The stain on your skin is very noticeable – to say the least-- as it presumes a dark color. I did have success with hand creme, working it in repeatedly, and then using a scrub brush with soap.
OK, that’s the tip.
